“Knock Knock” is TWICE’s comeback single song that broke records for K-Pop girl groups. Their song did very well on the charts since the release date and achieved an “all-kill” (took the top spot on all eight major Korean realtime charts) within the first hour after it came out.
24 hours after the Music Video was released on YouTube, the group had reached 9,857,751 views on YouTube, which is the most that a K-Pop girl group MV has ever received in its first day.
According to SOOMPI, in the K-Pop group category as a whole, “Knock Knock” is also now the second fastest to hit 10 million views and received the second-highest views in 24 hours.
On October 30th, 2017, TWICE released their music video for “Likey,” which is the fun title track off their new album Twicetagram.
According to some portal news, “Likey” was composed by Black Eyed Pilseung and Jeon Gun, and was the group’s fourth collaboration with Black Eyed Pilseung. Several composers and songwriters participated in the album including the Korean members of Twice as lyricists and former Wonder Girls’ member Hyerim who co-composed the eighth track titled “Look at Me.”
This Music Video from the album that has Christmas-inspired visuals, debuted atop both Billboard‘s World Albums and World Digital Song Sales respectively (the group’s first number 1), making Twice the first female K-Pop act to lead on both charts. They also rose on the Heatseekers Albums as the album debuted at number 10, one position higher than Signal’s peak at number 11.
On April 9th, 2018, they released their fifth EP, What Is Love? with the single of the same title produced by Park Jin-young. The EP sold 335,235 copies in the first month and made Twice become the first female artist—and the fifth act—to earn a Platinum certification by the Korea Music Content Association (KMCA), for having sold over 250,000 copies.
In this year, too, TWICE performed a cover of The Jackson 5’s “I Want You Back” as the theme song to the Japanese film adaptation of Sensei Kunshu. The song was released as a digital single on June 15th, 2018, along with the music video.
What Is Love?
On April 9th, 2018, TWICE released their fifth EP, What Is Love? with the single of the same title produced by Park Jin-young.
According to SOOMPI, with composition and lyrics by Park Jin Young, “What is Love?” is a dance track expressing the curiosities and imaginations of girls who learned about love through books, movies, and dramas. It has a bright melody with up-tempo dance beats and trap genre rhythms.
TWICE broke their own record once again with this comeback. On April 18th, 2018, “What is Love?” had broken the K-Pop girl group record for 50 million views after breaking the record for 40 million views on April 15th.
Dance the Night Away
On July 9th, 2018, an expanded reissue of What Is Love? titled Summer Nights, along with its lead single “Dance the Night Away” written by Wheesung, was released. The single surpassed 100 million streams and sold 2,500,000 downloads on Gaon Music Chart, earning the group’s very first Platinum certification for a single both streaming and download making Twice the second act—to earn a Platinum certification for streaming, download, and album by the KMCA since certifications were introduced in April 2018.
According to SOOMPI, the evening after the Music Video was released, TWICE hosted a V Live broadcast to talk about their new release with their fans. The set of their show even matched the beachy background of their music video.
The members talked about the choreography for their new song, and Jihyo named it as their most difficult dance.
“When other people saw our choreography video, they worried and asked us how our energy is doing,” said Nayeon in the live stream.
TWICE also shared some stories about their music video filming. Mina said, “We were dancing on the sand, but we kept sinking deeper down into it,” and then recreated what it looked like. Nayeon commented, “During Mina’s part where it’s raining, it was fake rain. It was raining at the time, but when the filming started the sun suddenly came out. So they sprayed water down from above.”
And then, by July 10th, 2018, 24 hours after the release, the music video achieved 20,387,875 views on YouTube. TWICE broke their record again.
